can makehuman/MB-Labs be used to make a SPECIFIC human face from photos?
Tools like this are best viewed as a starting point, they are generally designed to provide a broad range of human shape variations rather than specific ones. Every human is slightly different and it is infeasible to provide parametric controls sufficient to capture all this variation. 

The idea should be to start with major proportions and work down to finer details, getting as close as you can in the tool and then switch to sculpt/manual modelling etc to refine. Textures also make a big difference, and neither makehuman or mb-lab provide much here, you may want to look at projection painting from photos if you can find some that are good enough.
